Modelos de frecuencia de choques para segmentos e intersecciones: Ruta 34 en Costa Rica

| description | The National Route 34 has a great relevance at national and international level because it allows crossing Costa Rica from border to border, without entering at the metropolitan area. Unlike previous studies, for the first time for a corridor in Costa Rica, models were made for segments and intersections simultaneously. This project includes countermeasures for the 16 segments and 11 intersections with greater expected crash frequency.The oadway safety management process indicated in the 2010 Highway Safety Manual was used in this investigation. The first three steps of the process were developed: network screening, diagnosis and selection of countermeasures. To perform the analysis, the method of expected crash frequency with empirical Bayes adjustment was used because the accuracy differs from other methods that considered data availability, regression-to-the-mean bias, and how the performance threshold is established.One of the main problems found on this road is the absence of facilities for pedestrians and cyclists as well as problems with access management, shoulder width, speed and design of intersections. |

La Ruta Nacional 34 tiene una gran relevancia tanto a nivel nacional como internacional pues permite atravesar Costa Rica de frontera a frontera, sin ingresar a la zona metropolitana. A diferencia de estudios previos, por primera vez para un corredor en Costa Rica, se realizaron modelos tanto para segmentos como para intersecciones simultáneamente. Se estudiaron los 16 segmentos y 11 intersecciones con mayor exceso de frecuencia de choques. El proceso de gestión de seguridad vial que se utilizó es el recomendado por el Manual de Seguridad de Carreteras del 2010, del cual se desarrollaron los primeros tres pasos: evaluación de la red, diagnóstico y selección de contramedidas. Para realizar el análisis se utilizó el método de exceso de frecuencia de choques esperado con el ajuste de Bayes empírico, debido a que se distingue de otros métodos por su precisión al considerar la disponibilidad de datos, el sesgo de regresión a la media y cómo se establece el umbral de desempeño. Una de las principales problemáticas encontradas en esta carretera es la falta de facilidades para peatones y ciclistas, problemas con la gestión de accesos, anchos de espaldón, velocidad y diseño de intersecciones.
